+MS Modulation Commands 35
+MS: (list of supported <mod> values), (list of supported <automode> values), (list
of supported <min_rate> values), (list of supported <max_rate> values), (list
of supported <x_law> values), (list of supported <rb_signaling> values)
For example,
+MS: (0,1,2,3,9,1`0,11,56,64,69), (0,1), (300-33600), (300-56000), (0,1), (0,1)
Subparameter Definitions
1. <mod>= A decimal number which specifies the preferred modulation (automode
enabled) or modulation (automode enabled) to use in originating or answering a
connection. The options are:
<mod> Modulation Possible Rates (bps) 1 Notes
0 V.21 300
1 V.22 1200
2 V.22 bis 2400 or 1200

Notes : 1. See optional <automode>, <min_rate>, and <max_rate> subparameters.
2. For V.23, originating modes transmit at 75 bps and receive at 1200 bps;
answering modes transmit at 1200 bps and receive at 75 bps. The rate is always
specified as 1200 bps.
The modem may also automatically switch to another modulation (automode), subject to
the following constraints:
a. The modem may not be able to automatically switch from the current
modulation (specified by <mod>) to some other modulation. For example
there is no standard way to automode from Bell 103 to V.23.
